I have a sign in front of the building, and try to keep a friendly or funny message up. I currently have "Walk-Ins Welcome - Surprise Me" on it. I really feel like that sign was responsible for 15 new clients this year. People are not afraid to come in. I have heard, "Surprise!" about 100 times since January. (That's gettin old and tired, not gonna lie.)
Below is a picture of what I had on there previously. My kids' friends got a kick out of it, but it caused some confusion, especially with one fella who was worried about me and my family issues. You win some, you learn some.
